SPECIFICATION forming part of Letters Patent No. 317,712, dated May 12, 1885.

Application led J une 18, 1884.

.To all whom it may concern,.-

Be it known that I,W1LL1AM M. BarsBnN, a citizen of the United States, residing in the city of Philadelphia, county ot Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Hydrocarbon-Injectors 5 and I do hereby declare the following lto be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and iigures ot' reference marked thereon, which form part of the specification.

In said drawings, Figure lis a longitudinal section of the complete injector. Figs. 2 and 3 are longitudinal sectional views of details. Fig. 4 is a detail section of a modification.

My invention has for its object to provide a simple and comparatively inexpensive construction whereby fuel in the form of hydrocarbon fluid may be injected into furnaces in such manner as to produce the atomization and vaporization ot the iluid as well as its intimate intermixture with the steam.

My invention consists in the peculiar construction and combination of parts constituting the injector, such partscomprisin g a tubular steam-supply with tapering nozzle, a surrounding'hydrocarbon-pipe, and a conical steamplug, said parts being relatively so arranged that the steam will issue in the form of a very thin annular jet, and in issuing will spread across the delivery ofthe hydrocarbon7 thereby producing suction in the hydrocarbon-pipe and minglingwith and acting upon the liquid, substantially as hereinafter fully described.`

Referring to the accompanying drawings, A designates a T-pipe, which forms the hydrocarbon-supply pipe, the branches A B being the inlet and the end G the discharge. Within the body of this pipe is the body b of another pipe of l form, having an inlet branch, b. The pipe b is of less diameter than the pipe A, leaving a narrow annular space between the two, forming the hydrocarbon-chamber, which is open at its discharge end, and from which the hydrocarbon is emitted in the form of a thin annular or tubular sheet or stream.

Within the pipe b is a plug or spindle, f, having a bearing in a nut, c, which closes up the rear end of the pipe, as shown, said plug Vdered eiiective at the point of discharge.

(No model.)

having an operating wheel or handle, c. The other end of said plug terminates in a conical head, d, which has a valve-seat in the Haring end a of the pipe b. This constructionV causes the steam, which is admitted through the branch b, to issue from the steam-pipe in the form of a daring annular jet, which, by due adjustment, may be made exceedingly thin or attenuated. The diameter of the widest part of the conical head d is greater than the internal diameter of the steam-pipe, but less than the internal diameter of the hydrocarbon-pipe, and hence, while said conical head spreads the steam so as to causethe latter to rush across the discharge of the hydrocarbonpipe, said head does not intercept nor impede the discharge of the hydrocarbon fluid. The steam in its passage across the discharge of the hydrocarbon-pipe produces a suction in said pipe, and draws the iiuid therefrom, striking such liuid as it emerges and atomizing and vaporizing it, the resultant gas or mingled vapors being injected into the furnace in condition admirably adapted for thorough and eli'ective combustion.

The device, though primarily intended for the injection of hydrocarbon uids, may be advantageously employed for injecting coal-dust.

I am aware that hydrocarbon-injectors have been heretofore constructed, and that con oidal devices have been employed as spreaders for the hydrocarbon iiuid; but my device differs therefrom in the construction ofthe steam-plug in the manner described to produce a flaring annular jet of steam, whereby I am enabled to increase or decrease, as necessary, the emission of steam without varying the size of the aperture for the discharge of the hydrocarbon, and without in any way impeding the flow from such discharge. It will be noted that the extent'of emission of steam is controlled by the conical head ot' the plug d, and that such emission isl regulated at the discharge end of the injector; hence, that the full pressure of the steam is secured and ren- It will be further noted that, owing to the relative proportions and arrangements of parts, the movement of the steam-plug does not interfere with the discharge of the hydrocarbon, or lessen or increase the opening for such dis charge, the low of hydrocarbon being regu- IOC lated by a valve in the branch; hence, by iirst regulating the supply of hydrocarbon, the amount of steam to be emitted therewith, which may vary with different conditions, can 5 be controlled bya simple movement of the steam-plug.

What I claim as my invention is as follows:

The hydrocarbon-injector herein shown and 1o described, the same comprising the hydrocarbon-pipe A, the steampipe b, and the adjustable steam-plug d, With conical or tapering head, the greatest diameter of said head being in excess of the internal diameter of the steam-pipe and less than the internal diameter of the hydrocarbon-pipe, and said plug being adjustable to control the discharge of steam Without affecting the outlet for the hydrocarbon, substantially as set forth.
